Anthropogenic disturbances simplify frugivory interactions in Amazonia
Frugivory interactions are essential ecological processes for the regeneration of tropical forests, ensuring ecosystem resilience following disturbances. However, little is known about how frugivory interactions are shaped by anthropogenic disturbances, especially in Amazonia – one of the most biodiverse ecosystems on Earth.

Tropical forests are being reduced by human activities. The use of fire for agricultural expansion generates areas dominated by the bracken fern Pteridium, where forest regeneration is slow. This may be caused by seed limitation, especially of animal‐dispersed seeds, due to the absence of seed dispersers from the forest in deforested areas, calling for

Toucans are among the most conspicuous and famous birds in the Neotropics, but numerous aspects of their biology remain poorly known. The Toco Toucan (Ramphastos toco) and the Chestnut-eared Aracari (Pteroglossus castanotis) are commonly found in central Brazil, where studies on their breeding are scarce.

Patterns of variation in fleshy diaspore size and abundance from Late Triassic–Oligocene
ABSTRACT Vertebrate‐mediated seed dispersal is a common attribute of many living plants, and variation in the size and abundance of fleshy diaspores is influenced by regional climate and by the nature of vertebrate seed dispersers among present‐day floras.

Examination of material representing the 24 previously named species and subspecies of Austrophilopterus resulted in recognition of only 6 of these as valid species and 18 as synonymies, including a previously established junior synonym and 17 new synonymies. These 6 species are redescribed and illustrated. One new species, A.

Constraints on avian seed dispersal reduce potential for resilience in degraded tropical forests
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal is fundamental to tropical forest resilience. Forest loss or degradation typically leads to defaunation, altering seed transfer dynamics and impairing the ability of forested habitats to regenerate or recover from perturbation.

Toucans and toucanets are widely distributed in the Neotropical Region. Some species perform regional movements in search of food resources, but little is known about this behavior and the use of modified habitats.
